Graphing quadratics using vertex form

senteo pre-assess - prior knowledge 20 minutes
	- go over

google docs presentation - 10 minutes
	- definitions of quadratic function
	- differences in quadratic and linear
	- forms of a quadratic equation
		- vertex
		- standard
	- focus on vertex
		- examples

partner assignment - 45 minutes
	- vertex form activity on geo sketch
		- click and drag values to explore changes in parabolic characteristics, vertex, etc.
		- into a google docs form, enter 8 vertex form equations that satisfy specific characteristics
			- quadrant 1, open down; quadrant 3, open up; etc.

	- post results onto a group page on wiki
	- each group presents a problem and explains significance of constants and coefficients in their equations
	  with respect to its graph

independent assignment - 15 minutes->homework
	- given 5-6 graphs on a basic geo sketch file without sliders and manipulatives, derive the equations 
	  that match the graphs 
	- solutions are to be entered into a google form and submitted
